Figure 13 is the following sectional view of washing machine shown in Figure 1.

Washing machine 1 has the casing 2 that forms its profile, be suspended on washtub 3 in this casing 2 by suspension rod 4, the water supply installation 5 that is arranged on washtub 3 tops, supplies water in washtub 3 with the drainage arrangements 6 of water from washtub 3 inner discharges, and is operated this washing machine 1 necessary operating portion 70.As the front, operating portion 70 was arranged on the face side of top 2e when the front 2a of washing machine 1 used, and the user operates in its front.

In washing machine 1 of the present invention, washtub 3 is obliquely installed, and its top is outstanding to face side.Adapt therewith, outstanding shape is also made on the top of casing 2 face side.

By washtub 3 is obliquely installed like this, as shown in Figure 2, the input port of washtub 3 is compared with the existing washing machine shown in the dotted line, relies on the front with the size that is equivalent to L1, and owing to washtub 3 tilts, so its bottom is seen clearly easily.In addition, the bottom rear part size L2 that also moves up.Consequently, standing in positive user can take out washings easily.

Below, be elaborated with reference to Fig. 1.

Washtub 3 has by the outer bucket 31 of round-ended cylinder shape being arranged, the interior bucket 32 that the coaxial cylindrical shape washing and dewaterings that are installed in the outer bucket 31 are used, and the agitator 33 of bucket 32 inner bottom parts in being located at as some suspension rods 4 supporting of suspension arrangement.Interior bucket 32 is arranged in the outer bucket 31 rotationally.The side face of the interior bucket 32 of this embodiment has many aperture 32a.Interior bucket 32 is driven by the drive unit 34 with motor 35 grades with agitator 33.In washing and when flushing, have only agitator 33 to rotate to a direction or both direction, when dehydration, agitator 33 with interior bucket 32 to a direction high speed rotating.But, also can when washing, allow water store in interior bucket 32 not at the side face formation aperture 32a of interior bucket 32, the interior bucket 32 interior contained water of washings are got rid of outside bucket, outflow by centrifugal force during dehydration from the top of interior bucket 32.

Washtub 3 is arranged to positive face tilt.In other words, the central axis C L of outer bucket 31 tilts by predefined angle K with respect to plumb line VL.In the scope that above-mentioned angle of inclination K is above at 5 degree, 20 degree are following, because like this to the taking-up that makes things convenient for washings and prevent that casing 2 maximizations all are beneficial to.Why will be like this, be because the angle of inclination as less than 5 degree, then the inclination of washtub 3 is abundant inadequately, just can not very easily washings be taken out.Along with the change of angle of inclination K is big, the taking-up of washings also becomes conveniently.But surpassed 20 degree as angle of inclination K, then because washtub 3 too tilts, washtub 3 also becomes greatly the maximization so casing 2 will become to the outstanding amount in front.When angle of inclination K be set at especially 8 degree above, 12 when spending following scope, washings is convenient to remove, and clean ability also can be the same with existing washing machine, so preferably set for like this, and, casing 2 also can be inhibited to the overhang of face side, and the washing machine 1 that can enable to put into the anti-water pond of existing specification size does not have irrational place in actual applications.In this embodiment, angle of inclination K is set at about 10 degree.

Suspension rod 4 comprises 2 preceding suspension rods 41 that hang first suspension arrangement of washtub 3 incline direction downsides (face side) as allowing washtub 3 tilt, and 2 rear suspension bars 42 of second suspension arrangement of conduct suspension washtub 3 incline direction upsides (rear side), preceding suspension rod 41 is different with the structure of rear suspension bar 42.As Fig. 1 and shown in Figure 3, the front portion of preceding suspension rod 41 in casing 2 connecting the support unit 28 as the front portion of the flange part 31m of the support unit of outer bucket 31 front portions and casing 2.The rear portion of rear suspension bar 42 in casing 2, the support unit 29 at the rear portion of the flange part 31u at bucket 31 rear portions and casing 2 outside connecting.The flange part 31u of rear suspension bar 42 usefulness and the distance of support unit 29 are shorter than the distance of the flange part 31m of preceding suspension rod 41 usefulness and support unit 28, for example are roughly its half.

The flange part 31m of outer bucket 31 front portions is located near outer bucket 31 bottoms.Flange part 31m is provided with a pair of, and this a pair of flange part 31m is arranged on the position of outer bucket 31 side face left and right directions symmetries, is that the center angle at center becomes about 90 degree with the central axis C L of bucket 31 in addition.

The flange part 31u at outer bucket 31 rear portions is arranged near outer barrel 31 the central authorities that central axis C L measures.The flange part 31u at outer bucket 31 rear portions is provided with a pair of, measures from left and right directions, and the interval (the size L4 of Fig. 3) between this a pair of flange part 31u is narrower than the interval (the size L5 of Fig. 3) of anterior flange part 31m.

Each has the recess shape gooseneck bracket of accepting suspension rod 4 ends and with pack into the breach of recess of suspension rod 4 these flange parts 31m, 31u.

The support unit 28,29 of casing 2 is arranged on the sheet metal of four jiaos of its inside upper part, with the last ora terminalis riveted joint of the master unit 21 of casing 2. Support unit 28,29 is the same with flange part, has the recess shape supporting base of accepting suspension rod 4 ends and with pack into the breach of recess of suspension rod 4.

As shown in Figure 4, preceding suspension rod 41 has the cramp bar 43 that hangs outer bucket 31, and is located on the cramp bar 43, weakens the antihunting device 45 of the vibration of outer bucket 31.The upper end 43a of cramp bar 43 is contained on the support unit 28 by buffer unit 46, is provided with antihunting device 45 on the 43b of the bottom of cramp bar 43.The flange part 31m of the upper end 451a of the container 451 of this antihunting device 45 bucket 31 outside nonwoven fabric (not expressing among the figure) is supporting.

Antihunting device 45 utilizes along with piston 452 moves and the air flow resistance of generation in container 451, weakens the vibration between piston 452 and the container 451, promptly so-called air damper.Antihunting device 45 is the devices that at suspension rod 4 length directions elastic force arranged, flexibly keeping length of boom at its length direction.In other words, antihunting device 45 has the container 451 that internal separation goes out air chamber 451c, but partitioned bottle 451 and at the piston 452 of interior mobile vibration-proof rubber system, and relax the spring 453 that piston 452 is hit.Be formed with the intercommunicating pore 451b that is communicated with inside and outside the air chamber 451c on the container 451, cramp bar 43 imports in the container 451 by this intercommunicating pore 451b, and the bottom 43b of cramp bar 43 is connected with piston 452.When outer barrel 31 vibration taking place, the side face of piston 452 is rubbing and is moving in container 451, and air moves in container 451 by the hole on the piston 452 (expressing among the figure), inside and outside intercommunicating pore 451b discrepancy container.At this moment, the friction of piston 452 and the flow resistance of air have suppressed relatively moving of piston 452 and container 451, and consequently, the vibration of outer bucket 31 is suppressed.Antihunting device 45 also can adopt other known structure except air damper.

As shown in Figure 5, rear suspension bar 42 has a pair of interconnecting to hang outer barrel 31 cramp bar 43,44, and is arranged on the above-mentioned antihunting device 45 between a pair of cramp bar 43,44.Part to identical with preceding suspension rod 41 has given same symbol.The upper end 43a that is positioned at the cramp bar 43 of upside is installed on the support unit 29 by buffer unit 46, and the container 451 of antihunting device 45 is fixed on the bottom 43b of cramp bar 43.The upper end 44a that is positioned at the cramp bar 44 of downside is connected on the piston 452 of antihunting device 45, and the bottom 44b of this cramp bar 44 is supporting the flange part 31u of outer bucket 31 by buffer unit 46.

In addition, rear suspension bar 42 also can adopt structure for example shown in Figure 6.In other words, change cramp bar shown in Figure 5 43 into support unit shown in Figure 6 47.Support unit 47 is bent to form with the mid portion of a wire rod.Near support unit 47 upper ends, another end 47b of the wire rod of reeling on the end 47a of wire rod, on the 47c of the bottom of support unit 47, above-mentioned mid portion forms the disc spring shape, reels, is fixed on the outer peripheral face of container 451.On the outer peripheral face of container 451, be formed with the annular convex 451d of the above-mentioned mid portion of carrying.In this case, the power that support unit 47 is subjected to can not form the pulling force that acts on container 451, even therefore the resinous container of anti-pulling force is not fragile yet.

In addition, rear suspension bar 42 also can be as shown in Figure 7, adopts the structure of having only a cramp bar 43 the same with preceding suspension rod 41.For example, can consider to adopt installation method with preceding suspension rod 41 turned upside down shown in Figure 4, the bottom of the container 451 of antihunting device 45 is contained on the support unit 29, antihunting device 45 is contained on the upper end of cramp bar 43, the flange part 31u of the outer bucket 31 of the bottom of cramp bar 43 supporting.

Like this, above the antihunting device 45 of rear suspension bar 42 is arranged on the support unit 29 of casing 2, perhaps under the situation between support unit 29 and the flange part 31u, can makes and guarantee that the fore-and-aft direction space is more or less freely.Also the top of flange part 31u can be reasonably the antihunting device of rear suspension bar be arranged on, thereby the maximization of casing 2 can be prevented.

As washtub 3 is to tilt, after putting into water and washings, just washtub 3 has the tendency that shifts forward.This be because, for example shown in Fig. 8 (a), suspension rod 4 all is contained in the bottom of outer bucket 31 before and after can inferring, in the washtub 3 in case when adding load such as water, the center of gravity of rotor 3 just to the front upper place move (with reference to the center of gravity G1 before moving with mobile after center of gravity G2), the thing followed is that preceding suspension rod 41 suffered gravity increase, and washtub 3 just has the tendency that shifts forward, and causes the maximization of casing 2.

Shown in Fig. 8 (b), in the present embodiment, because the flange part 31u at rear is than the more close upper opening 3a of central axis C L of the outer bucket 31 in flange part 31m edge in the place ahead, therefore the intersecting angle D1 of the bearing of trend of rear suspension bar 42 and plumb line VL big than shown in Fig. 8 (a), consequently in the suffered gravity W of rear suspension bar 42, around support unit 29, locate to make the composition WR of the power of rear suspension bar 42 rotation directions to increase.As a result, because washtub 3 pulled to the rear more forcefully, so washtub 3 is suppressed because of the tendency that concerns antedisplacement of load, thereby can prevent the maximization of casing 2.Because this effect is to obtain by in higher position flange part 31u being set, so can not cause the maximization of casing 2.

As shown in Figure 9, in the present embodiment, the interval L4 between the flange part 31u at rear is than the narrow (L4＜L5) of the interval L5 between the flange part 31m in the place ahead.Like this, when the support unit 28 in the position of the support unit 29 at casing 2 rears and the place ahead is the same, owing to see that in the above the gradient D2 of rear suspension bar 42 fore-and-aft directions is bigger than the gradient D3 of preceding suspension rod 41, so the supporting rigidity of rear suspension bar 42 fore-and-aft directions can be improved.This is for the displacement of washtub 3 at its bearing of trend because of suspension rod, main rigid support by the antihunting device spring, to the intersect vertically displacement of direction of its bearing of trend, then by with the rigid support of flange part or support unit contact portion, usually, the latter's rigidity is than the former height.For example, when front and back to displacement when acting on rear suspension bar 42, big as above-mentioned gradient D2, then big in the displacement with the intersect vertically composition of direction of bearing of trend, therefore can support with higher rigidity, consequently, the vibration of fore-and-aft direction can be inhibited.

In the present embodiment, suspension rod 4 fronts and back respectively have two, but are not limited thereto, and for example, can have one in the front, and the back has two, and totally three, perhaps the front has two, and the back has one, totally three.

Also have, preceding suspension rod 41 is that antihunting device 45 is arranged in the bottom, but also is not limited thereto.For example, can be the same with rear suspension bar 42 shown in Figure 5, antihunting device 45 is set in the centre.

In the present invention, in order to allow washtub 3 tilt forward and backward suspension rod 4 structure differences.Like this, the support unit 28,29 of casing 2 can be arranged on, and for example sees the position that is roughly foursquare bight from above, and consequently support unit 28,29 being provided with in casing 2 can be the same with existing washing machine.

As shown in figure 10, casing 2 has front 2a, left surface 2b, right flank 2c, back side 2d and top 2e, the whole box-shaped that roughly is cuboid that is shaped as.Casing 2 has left surface 2b, right flank 2c and the integrally formed master unit 21 of back side 2d, another parts front plate 22 of separating with this master unit 21, it is as the front member that forms front 2a, and be contained in front plate 22 and master unit 21 tops, the top top panel 23 of formation, and supporting front plate 22 and the bottom of master unit 21, the bottom member 24 of formation bottom surface.

Master unit 21 is bent to form by single metallic plate, and left and right side 2b, 2c forwards extend from the left and right sides edges at two ends of the back side 2d of casing 2, a pair of front face 21a from this left and right side 2b, 2c as mutually near extending.Between this a pair of front face 21a, be formed with the opening 21b that safeguards drainage arrangement 6 usefulness such as grade, above this opening 21b, be provided with the interconnective girth member 25 in upper end simultaneously with the front face 21a of master unit 21.

The a pair of front face 21a riveted joint of girth member 25 and master unit 21 is reinforced the circumference of opening 21b, makes master unit 21 and then the rigidity of whole casing 2 is improved.The central portion of these girth member 25 left and right directions is more outstanding to face side than the both ends of left and right directions, in order to avoid clash with the top of washtub 3 face side, the bottom 25a of above-below direction is more outstanding to face side than top 25b, forms the cross sectional shape that is roughly the L font.This girth member 25 with part to the outstanding shape of face side is because consolidation effect is good, more satisfactory.

Above-mentioned support unit 28,29 is riveted on four jiaos of master unit 21 upper ends.This support unit the 28, the 29th is used for installing the parts of suspension rod 4, and the function of reinforcing 21 4 jiaos of master units is also arranged simultaneously.Be positioned at the support unit 28 in the place ahead and the front face 21a of girth member 25 and master unit 21 and be riveted together the reinforcement feature of double as girth member 25 and master unit 21 coupling parts.

Front plate 22 is that the parts that cover master unit 21 the place aheads are that the fore-end of the positive 2a of casing 2 and left and right side 2b, 2c is integrally formed.Front plate 22 can form with ester moulding processing or with known methods such as metallic plate calendering processing.Front plate 22 is the exterior member of washing machine 1, and is used for covering above-mentioned maintenance opening 21b, is contained in separatably on the master unit 21.That is to say, be provided with the hook portion 22f (only expressing a part among the figure) of a plurality of downward extensions at the back side of front plate 22, the front end of this hook portion 22f hangs among the fastening hole 21f of front face 21a of master unit 21, and front plate 22 is contained on the master unit 21.

The bottom 22a of front plate 22 roughly becomes vertical to launch at above-below direction.Begin to give prominence to towards face side towards the top in the middle of front plate 22 above-below directions, its top 22b tilts, and is high more outstanding to face side more in the above-below direction position.

Bottom member 24 has the top 24a that is connected with master unit 21 bottoms with front plate 22, the bottom 24b that falls in than top 24a at fore-and-aft direction, and the leg 24c that is contained in four jiaos of bottom 24b.

Top panel 23 is formed with the input port 23a that washings is put into, taken out washtub 3 in its substantial middle.The upper opening 3a of input port 23a and washtub 3 is relative to be formed to ground, and from front and back vector degree, the center of input port 23a than the center of top panel 23 more on the front.The circumference of input port 23a forms downward beveled, but switch is freely being adorned the lid 26 that covers input port 23a.

The face side end of top panel 23, have with the top 22b of front plate 22 outstanding that match, to the outstanding protuberance 23b of face side.On this protuberance 23b, be provided with operating portion 70.

Operating portion 70 has the operating surface 72 of arranging console switch etc., and constitutes the circuit board 71 (with reference to Fig. 1) that contains circuit such as console switch.Circuit board 71 with the watertight state be arranged at operating surface 72 below, have the control circuit that setting according to console switch makes the various piece running of washing machine 1.Operating surface 72 is towards the downward inclined-plane of face side, and operating surface 72 forms the top 2e that is formed by continuous inclined plane with the circumference of input port 23a.

In addition, as shown in Figure 1, top panel 23 is received at the rear of input port 23a water supply installation 5 is housed.

Water supply installation 5 has an end and is drawn out to casing 2 water supply pipes 51 outer, that be connected with the supply equipments such as washing pipe (not expressing among the figure) of outside, the feed water valve 52 of this water supply pipe 51 of switch, and be positioned at water supply pipe 51 the other end, form the water filling port formation parts 53 of the water filling port 5a of washtub 3.

As shown in figure 11, water filling port forms parts 53 by the washing agent of portion placed within is dropped into the container 53a of washtub 3 with the water that comes from the connector 51a that is being connected with water supply pipe 51, and the water that comes of guiding water filling port 5a, makes water integrally formed by deciding direction flowing water flow guide member 53b.The rear of current guide member 53b marks off water filling port 5a.Water filling port 5a is arranged on the top of washtub 3, and is arranged on the circumference of the upper opening 3a of washtub 3, near extreme higher position, washtub 3 upper end.The water that current guide member 53b guiding comes from water filling port 5a is pasting the inner peripheral surface of the interior bucket 32 of washtub 3, flows on the washings.

Like this, because water filling port 5a is positioned at the rear of washtub 3 upper opening 3a circumferences, water rearward flows out in washtub 3, therefore, water flows on the washings that is placed on washtub 3 rears, be seeped on the washings in washtub 3 the place aheads after accumulate washtub 3 bottoms, consequently, the washings in the washtub 3 can be wet through.

Flow on the washings owing to pasting washtub 3 inside, so after carrying out the centre dehydration between being in the suds, washings unclamps easily from the next water of water filling port 5a.

As shown in figure 12, the top of bucket 31 is formed with towards the outstanding spilling water chamber 31a of radial outside outside.Spilling water chamber 31a is in order to allow the water levels in the outer bucket 31 be no more than predetermined altitude setting, and spilling water chamber 31a and outer bucket 31 are interior to be communicated with by spillway hole 31b.Spilling water chamber 31a is set in place near the bight in the casing 2 of washtub 3 back.Be arranged on the spilling water chamber 31a of washtub 3 back, on the high position owing to the washtub 3 that is arranged on inclination, therefore can easily guarantee the water level in the washtub 3.Spilling water chamber 31a is connected with drainpipe 61 by overflow pipe 63.

As shown in Figure 1, drainage arrangement 6 has the drainpipe 61 that an end is connected with the water discharge outlet 31c of outer bucket 31 bottoms, and the draining valve 62 of this drainpipe 61 of switch.Water discharge outlet 31c is arranged on the leading section of outer bucket 31 bottoms, forms the lowest part of the outer bucket 31 of inclination washtub 3.Drainpipe 61 is more leaning on the position in the downstream of draining to be connected with overflow pipe 63 than draining valve 62, and the other end of drainpipe 61 (not expressing among the figure) is drawn out to outside the machine.

As shown in figure 13, near the water discharge outlet 31c of the bottom of washtub 3 draining valve 62 is being set, the position in the bottom by the back is being provided with motor 35.The parts that motor 35 is normally more towering, but because washtub 3 tilts, so its bottom is by the part ratio easier space of guaranteeing above-below direction of part on the front at rear, so can avoid irrational configuration.

In addition, the bottom of bucket 31 also is provided with the bascule 8 that suppresses vibration outside.

Bascule 8 is made of the container that marks off reception room and two containers that contain the particular fluid that is sealed in the reception room.Two containers be arranged on outer bucket 31 bottom centre relatively to both sides.

Liquid is that for example salt solution can flow in container for making it, and salt solution is filled 60～90% of vessel volume.Here why to adopt salt solution, be because salt solution than pure water than great, vibration-isolating effect is good, and can be antifreeze during low temperature.And employing salt solution, also it doesn't matter just in case leak.

Two containers see from above and all roughly are fan-shaped, with fore-and-aft direction opposing inclined direction on, form in longilineal mode, liquid can easily flow along its length direction.Because the length direction of container is oblique with respect to fore-and-aft direction, so liquid all can easily flow at fore-and-aft direction and left and right directions.

Bascule 8 is when dehydration starts etc., and interior bucket 32 grades reach before the high speed rotating, the function of performance vibrationproof damper.In other words, as the vibration that washtub 3 produces horizontal direction, the saline flow in the container, its reaction and viscous resistance have suppressed the vibration of washtub 3.Because container is fan-shaped,, can also suppress the vibration of outer bucket 31 rotation directions so liquid flows along fan-shaped.Also have, because a pair of container is symmetrically arranged, therefore the inhibition of vibration is effective.The shape of container is not limited to above-mentioned qualification, and the washtub 3 that can set inclination is fore-and-aft direction vibrations, and the shape of extending at fore-and-aft direction just can at least.

Because bascule 8 is made of container, so so long as the shape that liquid can flow just, its free degree is very high, consequently can be arranged in the space of washtub 3 bottoms.Why bascule 8 is arranged on the bottom, is because can avoid the maximization of casing 2 flat shapes like this.

This washing machine 1 is when washing, flushing and dehydration running, and washtub 3 keeps tilting.

When washing, by water supply installation 5 water is injected in the washtub 3 from water filling port 5a earlier, then, agitator 33 rotates, washings is stirred, at this moment, because washtub 3 tilts, so can stir fully.

Can infer in the washtub 3 that tilts, washings deflection front lower place, when dehydration started, washtub 3 will vibrate.Particularly on suspension rod semi-finals power ground washtub 3 is pulled under the situation at rear, this possibility is bigger.In the present embodiment, utilize narrower at interval rear suspension bar 42 and bascule 8, the vibration in the time of can suppressing to dewater fully.

As shown in Figure 2, according to present embodiment,, stand in the user of face side and can be easily take out washings from the upper opening 3a of washtub 3 because washtub 3 tilts to face side.In addition, because washtub 3 tilts to face side, so the bottom of washtub 3 particularly from face side, can come into plain view, consequently the taking-up of washings is very easy to, and can confirm to have or not the washings that does not take out easily.Therefore, can make washing machine easy to use 1.

Also have, as shown in Figure 1, owing to have only the top of front 2a of casing 2 outstanding, the bottom of the front 2a of casing 2 falls in relatively, so the user is when face side is walked close to washing machine 1, and obstacle can not caused in the bottom of front 2a.Therefore, user's the upper part of the body can be unlikely to far from washtub 3 bottoms that tilt, thereby make the taking-up of washings convenient more near washing machine 1.Particularly, the bottom 24b of polycrystalline substance 24 and leg 24c geometric ratio operating portion 70 be more by the rear, thus the user when face side is walked close to, leg 24c etc. can not cause obstacle.

Because have only top and the outstanding of washtub 3 of the front 2a of casing 2 to match, outstanding to face side, so the size of the bottom of casing 2 can be the same with existing washing machine.Consequently, washing machine 1 of the present invention can be put into the anti-water pond of making by existing washing machine specification size.

Because washtub 3 is to be in heeling condition for a long time, so do not need to switch the structure of heeling condition, the structure of washing machine 1 can be simplified, and is difficult for producing fault.

Also have, as shown in figure 10, because it is different parts that casing 2 forms the master unit 21 of front plate 22 and formation left and right side 2b, 2c etc. of the front 2a of outstanding shape, so master unit 21 can adopt the simple structure identical with existing parts, consequently can make at low cost.Because front 2a gives prominence to, so, make its outstanding processing just easily as long as to front plate 22 special treatments.Consequently, can prevent the raising of the processing charges of casing 2.Here, even the part of side is formed on the front plate 22, also can obtain same effect.

Because operating portion 70 is arranged on the protuberance 23b of top panel 23, so the user can operate operating portion 70 from face side easily, and sees the content of operating portion 70 easily clearly.

Because the operating surface 72 of operating surface 70 is the inclined-planes that tilt to face side, so more convenient to operate, the easier operating portion of seeing clearly can improve operability.

Because it is master unit 21 can be bent to form with a metallic plate with existing the same, therefore easy to process, cheap.

Owing to there is the peripheral part of 25 couples of opening 21b of girth member to reinforce, therefore make master unit 21, and then the intensity of casing 2 is strengthened, can suppress to rock and vibrate.Particularly to the outstanding girth member 25 of face side, because the rigidity height, so effective.

Owing to can not produce with washtub 3 to the outstanding girth member 25 of face side and conflict, even therefore shake and vibrate, washtub 3 is also very little with the possibility of girth member 25 damages.Here so-called the conflict mutually is meant and do not contact in the normal state, do not collide, and under the bigger state of vibration, contact is admissible with collision for the moment.

In addition, washtub 3 has the interior bucket 32 of outer bucket 31 and washing and dewatering bucket usefulness, so when being applied to automatic washing machine 1, can make washing machines 1 good, that washtub 3 tilts.Such automatic washing machine only needs after washing finishes washings to be taken out, so better effects if.

As long as in the scope of the angle of inclination of washtub 3 5～20 degree, take out washings just easily from washtub 3, and casing 2 can not tilt to increase yet with washtub 3.

As mentioned above, adopt the washing machine 1 of present embodiment, the taking-up that just can be made into washings is washing machine 1 very easily.And the not increase of the outward appearance of washing machine 1, washing machine 1 can be positioned in the anti-water pond of size for existing specification.Because the long-term heeling conditions that keep of washtub 3, therefore can make simple in structure, fault washing machine 1 seldom.

In the above-described embodiment, washing machine 1 is that the washtub 3 of dual structure is suspended on the single-tub washing machine on the casing 2, but is not limited thereto.For example, washing machine also can be the two-tub washing machine with personal cleansing bucket and dehydration barrel, and the personal cleansing bucket can be the bucket that the single structure of agitator is arranged at the bottom, also can be to be suitable for personal cleansing bucket of the present invention.

In addition, do not changing in the scope of the inventive concept, can carry out various design alterations.
